WebIn a fourth order filter the gain of the first section is 1.152 while that of the second section is 2.235. These gain values are necessary to guarantee Butterworth response and must remain the same regardless of the filter cutoff frequency. Also, the overall filter gain is equal to the product of the individual voltage gains of the filter sections.

WebMay 19, 2024 · Fourth-order Low Pass Butterworth Filter If the gain of both filters is set at 1.586, the voltage gain will be down 6 dB at the cutoff frequency. We can get a more flat response by choosing different values of voltage gain for both stages. WebAs a suggestion: Design a 4th-order notch filter where the zeros on the unit circle have multiplicity 2. They are ‘double zeros’. As before, your filter should be designed to remove 500 Hz when operating at a sampling rate of 8000 samples/second.
